a) you are on a windows-based server
b) you are using a separate WordPress URL vs Site URL under General Options?

I have the same problem. It seems to be random. I uploaded 22 images this morning and two show as ?. It happened last Thursday as well. I uploaded lots of images, but two or three refused to show.

I also noticed that all the images in that gallery show a date of Jan. 1, 1970. The Jan. 1 date seems to be throughout as well. It’s not every image, but it is there at least once in every gallery I checked.

Image gallery suddenly not showing on my website. Updated to latest WordPress version this morning. Don’t know if there is conflict, didn’t check image gallery before update. May just revert to older version of NextGen

Simple work-around for those who don’t want to downgrade back one of the earlier versions:

1) Create a directory in your “wp-content” folder that you will use to upload your images to.

2) Upload the images you want to that folder using either FTP, your webhost’s file management system, or through the WordPress Media Uploader. (NOTE: Depending on how you have your WP installation setup, if you use the WP Media Uploader, your images will either end up)

2) From the WordPress backend/admin menu, go to the “Add Gallery/Images” sub-menu in the (NextGen) “Gallery” menu.

3) Under the “Upload Images” panel, you’ll see the “Import Folder” panel. Click it to open it up.

4) Navigate to the new folder you just created to upload your images.

5) Select that folder, and click the blue “Import/YOUR_FOLDER’S_NAME” button.

6) Next, click on the “Manage Galleries” sub-menu.

7) You should see the name of the folder you used to upload your images as the name of a newly created gallery. Click the name of this gallery.

8) Click the checkbox next to “ID” to select all of the images you’ve just uploaded from that folder.

10) Select the gallery you want to move the images to, and click the “Ok” button.

You should now have all of the new images you uploaded in the gallery you need. One thing to note is that if you use the WordPress Media Uploader to upload your images, you will end up with about 3 copies of the same image at different resolutions, so make sure that if you use WordPress to upload your images, you only select the ones you want to move to your gallery in Step 8 (instead of checking the “ID” checkbox to select all of the images).

Hope this helps anyone else encountering this problem, and if anyone figures out how to fix the problem so we don’t have to use this method to upload images, PLEASE POST IT! Thanks!

Having the same problem (linux server) but when I click on Overview > Images it states ‘You do not have sufficient permissions to access this page.’ – but I am the admin with all the relevant permissions.

We are on a linux server. We are just using the site url. I’ll create a support a bug report. It sounds like there are more than just a few people experiencing this issue… 🙂 cry! I don’t think I want to go back though, the update eliminated 3 other issues I was having. We are using the skirmish theme btw.

Im experiencing this issue as well. I’m using WP 3.6 and NextGen 2.0, and my site is on Linux. After creating a gallery and uploaded images, or just added images to an existing gallery. The images are not displayed.

So I tried to create a bug report Erick as asked… but it is asking me to create a wrike.com account? is this legit? I filled out the form and clicked send and got an email as follows…

Okay so I just did the latest update this morning. Now I am attempting to upload images and it is giving me 0 percent uploaded error… where before it would upload and say it was 100% but nothing would show up and the meta data would be wrong as above. I am comfortable uploading the images via .ftp as suggested above, but I’m helping a friend set up her blog for her illustrations and she has no experience with .ftp so I wish the plugin would just work 🙁 I’m going to browse the support threads and see if I can find a solution. – Cindy
